Time it takes light from sun to reach earth? However, the surface of the earth is not exactly 1 AU from the surface of the sun. Plus, the Earth-Sun distance varies throughout the year. On February 4th, 00:00 UTC, the sun surface to earth surface light-time was 492.489 seconds (8 minutes, 12.489 seconds).

- We orbit the Sun at a distance of about 150 million km. Light moves at 300,000 kilometers/second. Divide these and you get 500 seconds, or 8 minutes and 20 seconds. This is an average number. Remember, the Earth follows an elliptical orbit around the Sun, ranging from 147 million to 152 million km. At its closest point, sunlight only takes 490 seconds to reach Earth.

Why does it take 20,000 years for light to reach the surface of the Sun from its core, but just 8 minutes to reach the surface of the Earth? Originally Answered: How do we know that it takes a photon around 100,000 years to reach the surface of the sun from it's core? We don’t. However, it is a calculation based on how many atoms absorb a photon and re-emit a photon before reaching the surface of the sun.

How Long Does it Take Sunlight to Reach the Earth? Sunlight travels at the speed of light. Photons emitted from the surface of the Sun need to travel across the vacuum of space to reach our eyes. The short answer is that it takes sunlight an average of 8 minutes and 20 seconds to travel from the Sun to the Earth.…..Here's the math. We orbit the Sun at a distance of about 150 million km.

How Long Does It Take to Get to the Sun? Apollo 10, the fastest manned spacecraft, traveled 24,790 mph. At that speed, it would take about 156 days to reach the Sun. The unmanned NASA New Horizon probe traveled away from the Earth on its path to Mars and beyond at 36,373 mph. If it travel to the Sun, it would have taken just over 106 days to reach it. It takes light approximately 8 minutes and 20 seconds to travel from the Earth to the Sun.

Does Starlight Require Millions of Years to Reach the Earth? Does Starlight Require Millions of Years to Reach the Earth? “When we look at the farthest visible star, we are looking 4 billion years into the past; the light from that star, traveling at 186,000 miles a second, has taken many years to reach us. First of all, I would dispute the chronological theory which suggests that the Universe dates at billions of years.

How Long Does It Take for Light From the Moon to Reach the Earth? The moon's distance from the Earth varies, but the average distance is approximately 240,000 miles. The sun is much further away at 93 million miles. It takes approximately 8.3 minutes for light from the sun to reach the Earth. In comparison, the sun's light takes roughly 5.5 hours to reach Jupiter.

Sunlight The ultraviolet radiation in sunlight has both positive and negative health effects, as it is both a principal source of vitamin D 3 and a mutagen. Sunlight takes about 8.3 minutes to reach Earth from the surface of the Sun. A photon starting at the center of the Sun and changing direction every time it encounters a charged particle would take between 10,000 and 170,000 years to get to the surface.

How long would it take for sound to travel to the sun from earth? How long would it take to get from the Earth to the Sun traveling at 30000 miles per hour? The average distance from the Earth to the Sun is about 93 million miles, so it would take about 3,100 hours at that speed, or a little more than 4 months. Edit Share to:

- It takes about 8 minutes for the suns light to reach the earth. The distance between the earth and the sun is really, really huge. And since light travels at 300000000 m/s, it takes it 8 minutes toreach the earth's surface. Voldemort · 9 years ago.

How long does it take for the earth to orbit the sun? The Earth's Orbit. It takes roughly 365 days for the Earth to go around the Sun once. This means that the Earth is rushing through space around the Sun at a rate of about 67,000 miles per hour! The time it takes for the Earth to go around the Sun one full time is what we call a year.

How much sunlight hits the Earth? Atmospheric Science with 30+ answers. The Earth receives an average solar insolation of 1361 Watts per square meter at the top of the atmosphere. But since much of this radiation is attenuated, this figure drops to an average of around 250 Watts per square meter at the surface (this figure still ignores clouds, however).

How long does it take sunlight to reach the Earth? The short answer is that it takes sunlight an average of 8 minutes and 20 seconds to travel from the Sun to the Earth. If the Sun suddenly disappeared from the Universe (not that this could actually happen, don't panic), it would take a little more than 8 minutes before you realized it was time to put on a sweater.

General Astronomy/Print version Light travels through space at just over 186,000 miles per second. The moon is just under 250,000 miles from Earth, so light from the Moon's surface has to travel more than one second (about 1.3 seconds) to reach us.Among other things, the astronauts left reflecting mirrors on the moon.ince moonlight is reflected sunlight, it originates at the Sun's surface 93 million miles from the Earth/Moon system. It takes about 8 minutes for that trip, so the short, final hop from the Moon to the Earth is trivial by comparison.

How long does it take for the suns rays to reach earth? Best Answer: When we're at apehelion (max distance, around July 4th), it takes about 8 mins and 29 secs. When we're at perehelion (min distance, around January 4th), it takes about 8 mins and 11 secs. Average time: 8 mins and 20 secs. The Sun's rays take 8.3784 minutes to reach the Earth, if you take the average distance between Sun and Earth. Only the Sun's warmth is slower than light, it's warmth takes about a week or two to reach the earth. This fusion process not only heats the Sun, it makes the sunlight we see here on Earth.

- How long does it take the light reflected from the moon to reach the earth?   light travels at 300,000,000m/s, the moon is roughly 375,000,000m away, so it takes light about 1.25 seconds to reach one from the other.etired US Navy officer, astronomy buff, history nut. Betelgeuse is a red supergiant star about 640 light-years from Earth. So light from Betelgeuse takes 640 years to get here. Here's an interesting fact; the star Betelgeuse is probably near the end of its life, and may explode in a supernova explosion any time.
